WILLIAM JOHN TEKIPPE, OF NEW HAMPTON, IOWA.

ROTARY ENGINE Application filed. January 16, 1908.

To all whom it may concern:

Be it known that I, WILLIAM JOHN Tn KIPPE, a citizen of the United States, residing at New Hampton, in the county of Chickasaw and State of Iowa, have invented a new and useful Rotary Engine, of which the following is a specification.

This invention relates more particularly to engines of the impact type.

The principal object is to provide a very simple and effective structure that can be readily manufactured, and will develop a high speed.

In the drawings :-Figure 1 is a side elevation of the engine. Fig. 2 is an elevation of one end of the same. Fig. 3 is a similar view of the opposite end. Fig. 4 is a longitudinal sectional view through the engine. Fig. 5 is a vertical cross sectional view.

Similar reference numerals designate corresponding parts in all the figures of the drawings.

In the embodiment illustrated, a casing is employed comprising a body 6 with end walls 7 bolted or otherwise secured thereto, said end walls being supported on suitable end brackets 8. The lower portion of this casing constitutes a cylinder member, being provided with a piston chamber 9, while the upper portion has a chest 10 for the reception of motive fluid. A valve casing 11 is interposed between the chest and the piston chamber 9. Motive fluid of any suitable character, v

whether steam, compressed air, gas or explosive charges are introduced into the chest 10 from any suitable source of supply through a suitable conduit as for instance a pipe 12.

A shaft 13 extends longitudinally and centrally through the piston chamber 9 and has bearings 14 in the end brackets 8. One end of this shaft has a suitable fly or drive wheel 15. A portion of said shaft within the cylinder member is provided with a revoluble piston comprising two end disks 16 and an intermediate disk 17 spaced from the end disks, thus providing two peripheral chan nels 18. The disk 17 can be divided into sections by a partition 17 if desired that will prevent the passage of motive fluid from one channel to the other. These various disks may be carried by a hub 19 that is suitably fixed to the shaft 13, the portion of said shaft within the casing being preferably squared, as will be evident by reference to Fig. 5. The inner opposing faces or sides of the disks 16 and 1.7 are provided with oppo- Specification of Letters Patent.

sitely inclined pockets 20, thus producing oppositely disposed shoulders 21. The shoulders of one channel are arranged in opposite relation to those of the other.

Leading from the valve casing 1.1 are two ports 22 that communicate with the two channels 18 and the motive fluid chest 10 is in communication with the valve casing 11 through two ports 23. Areciprocatory valve 24 having a path of movement longitudinally of the axis of rotation of the piston is connected to a stem 25 that projects through a suitable stuffing box 26, and one of the end walls 7 and has its outer end connected to a suitable actuating lever 27. This valve is so arranged that upon its movement in one direction, it will cover one of the ports 23 and the corresponding port 22, cutting off communication between the motive fluid chest 10 and one of the channels 18. This movement, however, uncovers the other port 23 and the corresponding port 22, thus opening communication between the motive fluid chest 10 and the other annular channel 18. The supply of motive fluid to the engine is controlled by a suitable throttle valve 28, and the eX- haust may be taken care of in any suitable manner, the exhaust ports of the present form of construction being illustrated at 29. Relief or safety valves 30 may also be employed if found desirable, said valves communicating with the channels 18.

The operation of the engine may be briefly outlined as follows. If the valve 24 is moved by the lever 27 to one end of the casing, and motive fluid is admitted to the chest 10, it will be evident that this motive fluid must pass through one only of the ports 23 and one of the ports 22, thus finding its way into one of the peripheral channels and striking the shoulders 21 will revolve the piston. To

reverse the engine, it is only necessary to swing the lever to an opposite direction, whereupon the other set of orts will be opened, while the first set will e closed, and conse uently the motive fluid will be admitte to the other channel, where it strikes against the oppositely disposed shoulders and turns the piston in an opposite direction.

From the foregoing, it is thought that the construction, operation and many advantages of the herein described invention will be apparent to thos skilled in the art, without further description, and it will be understood that various changes in the size, shape, proportion and minor details of construction may be resorted to without de arting from the spirit or sacrificing any 0 the advantages of the invention.

' Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In an engine of the character set forth, the combination with a cylinder member, of a rotary piston member located therein and having spaced peripheral channels with pockets located in the opposing walls of each channel, the pockets of the different channels being oppositely inclined, means for introducingmotive fluid into either channel independently of the other to rotate the piston in either of opposite directions.

2. In an engine of the character set forth, the combination with a cylinder member, of a shaft extending therethrougl'i, end. disks mounted on the shaft within the cylinder memberfan intermediate disk mounted on the shaft between the end disks and in spaced relation thereto, forming spaced channels,

said disks having shoulders on their opposing inner sides, the shoulders of one side of opposing sides being oppositely disposed to those of the other, and means for introducing motive fluid. into either channel independently of the other and against the shoulder.

3. In an engine of the character described, the combination with a cylinder member, of a reversible rotary piston operating therein, a valve casing formed in the cylinder member longitudinally of the axis of rotation of the piston and having a plurality of ports communicating with the cylinder member, a motive fluid chest located upon the valve casing and having independent ports in its end portions that communicate with the end portions of the valve casing, means for supplying motive fluid to the motive fluid chest, and a reciprocatory valve 0 crating in the valve casing longitudinally o' the axis of rotation of the piston, each end of said valve covering and uncovering one of the ports leading from the motive fluid chest to the valve casing and one of the ports leading from the valve casing to the cylinder member, said valve being snugly fitted in the valve casing.

4. In an engine of the character set forth, the combination with a casing having a piston chamber, a valve casing and a motive fluid chest therein, of a rotary piston operating in the chamber and having spaced peripheral channels provided with oppositely disposed pockets, said casing also having spaced ports leading from the valve casing and communicating with the channel, other ports leading from the motive fluid chest to the casing, a reciprocatory valve operating in the casing, each end of said valve being movable to a position to cover and uncover a set of the ports, a lever fulcrumed on the casing, and a connection between the lever and the valve.

In testimony, that I claim. the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
